Google Play Store allows you to download an application that will measure the ambient humidity and temperature of your surroundings in real time. Currently, the only devices that it will work on are those with Ambient humidity and temperature sensors, such as the Samsung Galaxy Note 3 and S4, according to the application description page. If you have either of those devices, you can begin learning how to measure the humidity on your supported Android device with Ambient Temperature and Humidity by Sensirion AG.

Steps

Part 1

Downloading and Installing Temperature and Humidity

1

Launch Google Play Store. Do so with a tap on its icon on your home screen.

2

Type in “Ambient Temperature” in the search bar. You can summon the search field by tapping on the magnifying glass icon at the top of the app screen.

3

Select the app when you see it. From among the results, select the one labelled “Ambient Temperature and Humidity” by Sensirion AG.

4

Download and install it. Tap on the “Install” button right below the app name to begin downloading and installing the app.

Read the permissions, and tap the “Accept” button at the bottom of the permissions window.

5

Launch the app. Just open the notification panel by swiping downward from the top of the screen, and tapping the Play Store notification that the app has finished installing.

You can also quickly do this by tapping the “Open” button that replaces the Install button in the application's page at the Play Store.

Part 2

Using the Application

1

Access the right screen. After you launch the app, you should be greeted with a splash screen, and taken to the main app screen. A notice will appear. Read it carefully, as it states the requirements for getting the most accurate reading.

2

Place your phone on top of a flat surface. Make sure it’s away from any strong wind sources, such as a fan, and keep it away from direct sunlight.

3

Wait five or so minutes to let the readings stabilize. Under the green temperature reading tile, you will see the Humidity Percentage. Once it becomes stable, take note of the humidity percentage as it should be the accurate measurement.

4

Place a Temperature and Humidity widget on your homescreen. You can configure a widget to be on your home screen to actively measure the humidity of your surroundings.

Tap and hold a blank area in your home screen, and select “Widgets” from the menu that pops up. Scroll down until you see “Temperature and Humidity,” and tap it. Select the unit of measurement (C or F), and set the refresh rate in seconds at the bottom. Tap on “OK,” and the widget should appear in the area you tapped and held.

The widget will show you the temperature reading on the left half and the humidity on the right half.
